All sellers making retail sales of taxable goods or services in Nebraska are required to register with the state and collect and remit sales tax. As Nebraska is a Streamlined Sales Tax state, out-of-state businesses without a sales tax obligation are encouraged to register for sales tax purposes.
Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force.
Calculate its kinetic energy in Joules. (b) A 1500 kg car loses speed (40.0 m/s to 30.0 m/s) over a distance of 100 m when sliding with the. wheels locked. Calculate the coefficient of kinetic friction between the tires and road. (c) A block of mass 23.0 kg is moved at a steady speed of v = 15.0 m/s with an.
